EARTH-AUGER.

SPECIFICATION forming part of Letters Patent No. 238,888, dated March 15, 1881.

Application filed July 30, 1880. (No model.)

To all whom it may concern Be it known that I, J AGOB H. GOULD, otAtwater, in the county of Portage and State of Ohio, have invented a new and Improved Earth-Auger, of which the following is a specification.

The object of this invention is to construct an anger adapted to bore in any kind of soil or mineral, and to combine with it devices for removing the soil or mineral from the opening made by the auger without raising the shaft thereof.

The invention consists of an auger provided with a series of bits of novel design, and of dirt-lifters or buckets combined therewith.

Figure 1 is a vertical elevation of the device. Fig. 2 is a cross-section on line a; m, Fig. Fig. 3 is a cross-section on line y y, Fig. 1. Fig. 4 is a cross-section on line 2 2, Fig. 1. Fig. 5 represents a side elevation of a loose dirt-lifter and a cross-section on line 10 to, Fig. 1, showing a plan of said dirt-lifter. Fig. 6 is a cross-section on line 0; c, Fig. 1.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents the shaft of the auger, of square cross-section, which may be made in two sections united at a. On the lower end of said shaft A a drill-bit, B, is secured, which in this case is nearly triangular, with scrolled or opposite curved edges, and is attached to the shaft A by pin b.

Immediately above the drill-bit B an earthbit, 0, consisting of a collar, 0, having three radial inclined cutters, c, is set about the shaft A, and prevented from excessive upward movement by the pin f, that is passed transversely through said shaft A. This bit 0 is designed to pulverize the earth, so that the dirt-lifters will take it up more readily in thedownward movement of the auger.

A combined dirt-lifter and earth-bit, D, designed for raising compact cake or stiff mud, is set about the shaftA and rests on the pin f, and is prevented from moving up too readily by the twist given to the lower part of the shaft A, as shown atf. This combined lifter and bit D consists of two crescent-shaped plates, d at, having their diagonally-opposite ends beveled andturned downward, to serve as cutters, as shown at d d, said plates d 01 being connected with each other so as to form a circle by the lugs 61 d, that project upward on opposite sides of the shaft A, and have a hook, d, engaged in them, to which book 61 is attached a rope or wire, D, that extends upward along the shaft A, and is designed to be within reach of the operator, who, by means of it, can draw said lifter and bit D up with a load of earth upon it to the top of the opening in the ground.

For raising sand or thin mud the combined dirt-lifter and earth-bit E is used in lieu of the lifter and bit D. Said lifter and bit E is comvided into four segmental cutters, g, each of which has a corner turned down, as shown in Fig. 1. A bail or loop, 9, is secured in the top of the box-socket g, and has attached to it a rope or wire, E, that extends upward parallel with the shaft A, and is made fast to the cross-handle H.

The screw-flanged ring is composed of a ring, h, of the same diameter as the broader part of the drill-bit B, and is provided on its outside with a flange-screw, h, and, is connected with its handle F by two parallel side rods, 71., that extend upward parallel with the shaft A. The handle F has an open center, and is fitted loosely over the shaft A at right angles thereto and near its top, as shown in Fig. 1, and said handle F rests on a washer ing the ring F, some of the weight of the shaft A will be supported thereon, and the pressure of the drill-bit B be thereby regulated, as desired.

G is a cylindrical block, set loosely about the upper part of the shaft A, and held in position by the rope or chain A, that connects it with the handle F. Said block Gr may be lowered or raised on the shaftAwithin the opening or bore in the earth, and by contact with the sides of said bore prevent the shaft A from swaying about when operating. As many of these supporting-blocks Gr may be used as may be necessary, according to the length of shaft to be supported.

Fixed on the top of the shaft A is a crosshandle, H, by means of which the said shaft A may be rotated, or bypower applied in some other well-known way, said handle H being held in place by a set-screw, H. The top of said shaft A terminates in a screw, 70, to which another section of shaft may be attached.

In operating with this device it is not necessary to remove it from the opening or bore made by it in order to remove the earth, 800., therefrom, as the combined lifters and bits D or E will receive the excavated earth and stones, 850., and can readily be pulled up and emptied when desired, and be restored to place again. Hence the apparatus need be drawn out of its place only when a new bit is required. The openings in these combined lifters and bits D E are of sufficient size to admit stones of various sizes.

Either lifter D E may be removed from the shaft A and replaced by the other at any time by first taking off the screw-flanged supportingring F and the steadying-block G.

I do not confine myself to the precise construction and arrangement of parts as herein shown, as it is obvious that they may be modified somewhat without departing from my invention.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent-- 1. An earth-auger constructed substantially as herein shown and described, containing the following elementsz'. 0., a drill-bit, an earthbit, a combined dirt-lifter and bit, a screwfianged supporting ring, and a steadying' block, as set forth.

2. In earth-angers, the crescent-shaped plates d 01, having their diagonall y-opposite ends beveled and turned down at d, and provided with lugs 01", having hook d,in combination with shaft A, having a twistjust above said plates,

as and for the purpose specified.

3. In an anger, the combination, with the shaft A, of the screw-flanged supporting-ring F, provided with rods h, and handle F", substantially as herein shown, and for the purpose described.
